A new satellite image has shown a marked increase in activity at a North Korean missile launch site, suggesting a new launch could be possible in the next few weeks.

The image at North Korea's Sohae satellite launch station was taken on November 23 and shows similar preparations as was seen before the failed April 13 attempt to launch a satellite on top of a long-range missile, the satellite imagery company DigitalGlobe analysis concluded.

"Given the observed level of activity noted of a new tent, trucks, people and numerous portable fuel/oxidizer tanks, should North Korea desire - it could possibly conduct its fifth satellite launch event during the next three weeks," according to the analysis provided to CNN.

According to the report, a source said that if there was a launch, it would likely be a long-range missile like the Taepodong-2 because the Sohae site is a long-range missile launch pad.

The United States has seen activity on the launch pad but does not believe a launch is imminent, U.S. military sources said. (ANI)
